BRICK-MACHINE.

SPECIFICATION forming part of Letters Patent No. 354,187, dated December14, 1886.

Application filed June .22, 1886.

T 0 aZZ whom it may concern:

,Beit known that I, WILLIAM Lanras GREGG, residing at Philadelphia, inthe county of Philadelphia and State of Pennsylvania, and a citizen ofthe United States, have invented a new and useful Improvement inBrick-Machines, of which the following is a full description, referencebeing had to the accompanying drawings, in which- Figure l. is a frontelevation. rear elevation. Fig. 3 is a side elevation showing that sidewhich is to the leftin Fig. 1. Fig. 4 is a side elevation showing theside which is to the right in Fig. 1. Fig. 5 isa vertical section atline :0 of Fig. 4, and Fig. 6 is a section at lineg of Fig. 1. Figs. 2and 3 are somewhat enlarged.

The leading object of my invention is to construct a. machine in suchmanner that it can be used both for making brick and for repressingbrick, which I accomplish as illus trated in the drawings andhereinafter described.

Those things which I claim as new will be set forth in the claims.

In the drawings, A is a bed-plate.

B B are housings.

C is the center shaft, supported in suitable bearings.

D is the pressurecam.

E E are two counterpressure cams.

F F are two sliding bars, held at a proper distance from each other bybolts a, on two of which bolts are rollers Z).

G is thepluuger, which is secured by bolts to the bars F. The top of theplunger is provided with a removable plate, 0.

H is a counter-pressure plate. which is provided with a removable plate,(Z, which enters the moldbox.

I are counter-pressure rods, to which the plate H is secured, which rodspass through guides J.

K is the mold-box, provided with asuitable lining, as usual.

6 are rollers supported on studs secured to the counter-pressure rods 1,one of which rollers is located in the eanrgroove in each of the cams EE.

f are rollers upon studs secured to the sliding bars F.

L are two horncams, one of which is se- Fig.2is a.

(No model.)

cured to each of the cams E E, which'cams L, coming in contact with therollers f, pull down the plunger at the proper time.

1 (see Fig. 6) is asteel facing upon a portion of the cam D.

M, Fig. 2, is a countershaft.

N is a spur-wheel on the main shaft 0.

O is a pinion on the counter-shaft M, which pinion engages with thespur-wheel N.

l? is a driving-pulley on the counter-shaft M.

Q is a hopper, the bottom of which is over areceptaele, h, for clay,(see Fig. 6,) consisting of four walls or sides, which rest upon a fixedplate, i. To the forward-end of this clay-1e ceptacle is attached ahead, j.

7c is a plate connected with the clay-receptacle, which closes and opensthe bottom of the hopper as such plate moves back and forth with thereceptacle h.

Z are two bars connected with the clay-receptacle it, one on each side.The rear end of each of these bars is provided with a pin, which entersa slot in the link m.

n is another link, and R is a projecting rod connected at its upper endwith the link a, and pivoted at its lower end to a bar, 0, (shown bestby dotted lines in Fig. 3,) which bar 0 is pivoted at p, and at or nearits center is provided with a roller, q, which is located in the groovein the cam S, (see Fig. 5,) which cam is upon the spur-wheel N.

r is a table onto which the brick are delivcred.

T is a narrow table projecting from one side of the machine andextending some distance into the machine, on which table brick to bere-pressed are placed and pushed into the machine.

s is a guidepieee attached to one side of the table T. This table andguide-piece may be made from a piece of angle-iron.

U is a plunger, the forward end of which is provided with a steel face,If. This plunger is located at right angles to the table T. It isprovided with a slot, block, and screws for adjusting the lost motion.It is operated by two .bellcrank levers, V, pivoted at a, the shortroller, 2;, located .in the cam grooves in the cams EE. The upper end ofeach lever is connected with a link, a, which links are connected withthe rod 1;.

arm of the levers being provided each with a ICO t is a tie-rod.

'w are couplings for thepurpose of adjusting the length of the rods withwhich they are connected.

to is a shaft which passes through the hopper.

b is a spring at one end of the shaft.

0 is a pulley on an enlarged part of the shaft a, the end of whichenlargement 1) is notched and engages with a correspondinglynotchedpiece, 02, secured to the shaft. The pulley c is driven by a cord, 6,which passes over the groove-pulley f. The devices last described servethe purpose of agitating the clay in the hopper.

The opening upon one side of the machine into which the brick that areto be re-pressed are placed is indicated by the letter A,

In the counter pressure plate are small openings to allow the escape ofsurplus clay, if any there be, in the mold-box.

h are hard-rubber washers beneath the nuts at the upper ends of thepressure-rods I, for the purpose of slightly relieving the strain uponthe parts in case there should be a little too much clay for themold-box.

The movements of the plunger G, which gives the pressure, and theplungers U, which push the brick to be re-pressed into the moldbox, areso timed that the forward end of the plunger U is at its extreme forwardlimit when the plunger G is rising to about the positionshown in Fig. 6,the inner end of the plunger U thus forming for the time being gne ofthe walls of the lower end of the mold- The operation is as follows:Supposing the machine to be in operation, andclay having been fed to themold-box K, as hereinafter described, the plunger will be forced up bythe action of the cam D against the pressureroller, the counter-pressureplate H being at the same timeheld stationary. \Vhen the .brick has beenpressed, the action of the cams E E will raise thecounter-pressureplate, and the action of the cam D will carry up the plunger G until itsupper surface comes in line with the table 1'. Then the head j will becarried forward, and the' brick will be swept off onto the table r. Atthe same time the receptacle it, being filled with clay, will be carriedforward to a point over the mold-box K, and

the clay in h will drop into the mold-box, the

plunger G having begun its descent, being carried down by the horn-camsL. At this time the plate will be beneath the bottom of the hopper. Bythe movement of the machine the receptacle h and head j will be againcarried back to the position shown in Fig. 6 and the counter-pressureplate H be brought down to the proper position for pressing anotherbrick. The head j and receptacle h are moved back and forth by theaction of the cam S, rod R, and links at n; The clay in the mold-boxwill then be pressed, the brick delivered, and a new charge of claybrought to the mold-box, as before described.

In re-pressing brick the operation is as follows: The brick to berepressed are placed one after another upon the table T and pushed intothe machine until the forward brick comes in line with the plunger U.Then the plunger, being operated by the bell-crank leversVand cams EE,will push the brick forward into the mold box, the plunger G at thattime being down. Then by the action of the cam D and plunger G, asbefore described, the brick in the mold-box will be re-pressed and willbe delivered upon the table r, as before described.

What I claim as new, and desire to secure by Letters Patent, is-

1. In a machine for making and repressing brick, a hopper, a slidingfiller-box, a plate to close the bottom of the hopper, a sweep to removethe brick to a table, the filler-box,

' plate, and sweep moving together, in combination with a mold-box,plunger G, counterpressure plate, shaft 0, cams D, E, E, and S, andconnections between the cam and sweep, all constructed, combined, andoperating substantially as and for the purpose specified.

, 2. In a machine for making and re-pressing brick, the combination of amold-box, a plunger, G, counter-pressure plate and rods, an opening toreceive the brick to be repressed, sweep U, to push the brick to themold-box, shaft 0, cams D, E, E, and S, and levers V, substantially asand for the purposes specified.

3. In a machine for making and re-pressing' brick, the combination of ahopper, a-fillerbox, a sweep to-remove the brick, a plate, k, to closethe lower end of the hopper, a moldbox, a plunger, G, counter-pressureplate and rods, an opening in the side of the machineto receive brick tobe re-pressed, a sweep, U, to push the brick to the mold, main shaft 0,cams D E E S thereon, connecting-rod R, and levers V, substantially asand for the purpose specified.

4. In combination with the hopper, an agitator consisting of a shaft,at, having a notched enlargement near one end, and carrying a pulley, c,a notched piece, d, upon the shaft a, and a spring, 12, substantially asand for the purpose specified.
